I changed the hostname of my mythfrontend. After that I got a 'clean'
mythfrontend system (with all the mythtv settings at their default
values). This way I was able to watch any channel on any input again.
Then I canged my playback profiles according to the way it was set
before. I am still able to watch any channel, so it works Ok.

The only thing I didn't change is the 'Sync to VBlank' option. It
is currently unchecked and I feel I may get problems if I try to
enable it...
